|MODELLING AND CONTROL OF STANDALONE WIND ENERGY CONVERSION SYSTEM - BOUZID Mohamed Amine, MASSOUM Ahmed, ALLAOUI Tayeb, ZINE SOUHILA|
In this paper, a Wind Energy Conversion System (WECS) is discussed. The power conversion system consists of a Permanent Magnet Synchronous Generator (PMSG), a rectifier and an inverter connected to the grid. An intermediate DC bus exists between the rectifier and inverter. This conversion system use the PMSG because of its high performances, small size and its low weight compared to induction generators...

|Design of UPQC with Minimization of DC Link voltage for the Improvement of Power Quality by Fuzzy Logic Controller|
Devices such as power electronics converters, inject harmonic currents in the AC system and increase overall reactive power demanded by the equivalent loads are presents non-linear characteristics. Also, the number of sensitive loads that require ideal sinusoidal supply voltages for their proper operation has increased. In order to keep power quality under limits proposed by standards, it is necessary to include some sort of compensation...

The power electronic related facilities may generate a large amount of harmonic current due to the nonlinear input characteristic. The harmonic current may pollute the power system causing problems such as transformer overheating, rotary machine vibration, voltage quality degradation, destruction of electric power components, and malfunctioning of medical facilities. In order to solve the problem of harmonic pollution effectively, the harmonic current can be suppressed by using a passive or acti...
